SH. m 5 a 6 m M w TW .t Th w/M mm f a Jfi x uJ B Patented June 3, 1941 UNITED STATES PATENT OFFICE ELECTRIC INCENSE vsroinzm 2 Claims.

Our invention relates to electric incense vaporizers, and has for its object to provide in combination means for holding a quantity of incense liquid such as some of the highly scented oils employed for that purpose, in combination with electric means for heating a surface and means for applying a film or desired quantity of liquid to the heated surface whereby it will be volatilized and caused to pass into any room or space where it is desired to have a pleasant odor, either for the sake of the odor itself or to override unpleasant odors such as may occur in kitchens, toilet rooms, and the like.

It is therefore, a principal object of our invention to provide a container for an incense liquid with means for introducing the liquid therein in combination with an electric heating unit having a surface adapted to be heated together with means for causing a limited amount of the incense liquid to be applied to said surface either before or after the same has been heated.

It is a further object of our invention to provide a'container for liquid incense in combination with a spring retracted plunger whereby the plunger may be caused to dip into the liquid within the container and then retract to normal position and to form within the plunger electrical resistances in an electric circuit whereby when the circuit is closed the surface of the plunger will be heated causing the liquid on the surface thereof to throw off fumes which have the characteristic odor of the liquid incense.

It is a further object of our invention to provide a container for liquid incense having a gravity discharge opening in association with a spring retracted plunger which is formed with an opening or cavity such that in retracted position the opening or cavity will be filled with the liquid and when it is pushed forward the small portion of liquid so trapped will have means for gravitating to an electrically heated pan, whereby said liquid will be caused to vaporize and the fumes will give off the desired pleasant odor.

It is a further object of our invention in connection with the forms of the invention above outlined, to provide a spring retracted switch closing member such that when it is pressed in it will close the switch and cause the surface of the liquid receiving member, whether it be pan or plunger, to become heated, and which, when pressure is removed, will release the switch to open the circuit so that excessive or too long continued heating of the evaporating surface will not take place.

The full objects and advantages of our invention will appear in connection with the detailed description thereof, and the novel features of our invention which produce the aforesaid beneficial results are particularly pointed out in the appended claims.

In the drawings illustrating our invention as specifically embodied in some of its forms,

Fig. 2 is a sectional plan view taken on line 2-2 of Fig. 1.

Fig. 3 is a sectional 33 of Fig. 1.

Fig. 4 is a sectional plan view taken on line 44 of Fig. 1.

Fig. 5 is a sectional elevation view showing a plan view taken on line modified form of our invention.

Fig. 6 is a sectional of Fig. 5.

Fig. 7 is a part sectional view showing a modified form of the liquid-releasing piston.

Fig. 8 is a section view showing still another modified form of liquid receiving and delivering piston.

Referring first to Fig. l, a base upon which are secured a multiplicity of spring fingers ll being fastened to the bases by screws I2. Removably held upon the base 10 is a container 13 which is held secured in position by means of a bolt and nut I4, Fig. 1, connected therewith. The container 13 may be of any desired shape, and as shown is semi-conical with a bottom cylindrical portion i5, a, narrowed portion 16 and a conical flange lip ll for getting the liquid into the holding chamber [8 inside of the member l3.

Removably held upon the base ID by means of the spring fingers I I is a. casing member l9 fitted with a conical annular flange 20 and semispherical top 2|. Secured to the top 2| by means of nuts 22 and 23 is a hollow threaded member 24. The member 24 is provided with a guide opening 25 in which is mounted a plunger shaft 26 having on its upper end a knob 21 surrounded by a compression coil spring 28. The spring 28 enters a tubular chamber 29 in the member 24 and engages an annular shoulder 30 on said member. By this means the plunger shaft 26 and parts carried by it are held in a desired retracted position. Threaded upon the end of shaft 26 by means of a nut extension 3| is a block 32 which carries a stem 33 of insulating material around which is wound a resistance wire 34 having connection with a circuit formed of wires 35, 36 and 36' passing through a switch block 37 and ultimately leading from the apparatus through cable 38 to be plugged in to line current in a customary manner. A spring retracted plunger member 39 comprises a self-opening switch adapted to make closing contact between wires 36 and 36' as long as the plunger member 39 is held down by an operator. Current will then be caused to pass through resistance wire 34 which will become suitably heated thereby.

In operation the plunger 21 will be pushed plan view taken on line 6-6 I0 is provided down to bring the stem 33 into the liquid within chamber [8, the stem being preferably pushed down to seat in the cylindrical extension l5 thereof. When the plunger is released the spring 28 brings the stem and its electrical windings 34 out of the liquid but covered with a film thereof such that when the resistance is heated. the film of liquid will be turned into vapor and the fumes thereof will escape through openings through casing Hi. In practice, the windings 34 on stem 33 may be covered with an insulating heat conducting sheath such as mica or sheet composition material to prevent any tendency of shorting between wires because of the liquid incense on the surface which is dipped into the liquid in chamber 18.

A spring finger guide M is held positioned by a screw member 42 and engages the side of the block 32 to guide it in its movements as stem 33 is thrust into and withdrawn from chamber l8.

In the form of invention of Figs. 5 to 8, a base of flattened oval shape as shown in Fig. 6 has secured thereto a casing 5| of similar ovalled shape. The casing 5i is provided with a longitudinal insulated partition 52 which divides the space within it into two separated chambers 53 and 54. Within chamber 54 is formed a receptacle 55 comprising a separate chamber 55 for incense liquid introduced thereinto through a feeding opening 51 closed by a screw cap 58. A tubular member 59 extends across chamber 54 forming a cylindrical passageway 50 extending through insulating partition 52 and provided with an air escape opening 6|, Fig. 5.

Within chamber 53 is located a pan 62 adapted to be heated by means hereinafter described. A tube 63 has its end 64 overlying the pan B2 and said tube has an upwardly turned extension 65 formed to give a cylindrical opening 66 into cylindrical passageway 60. A plunger stem 8"! has thereon a piston 68. The stem is provided with a head 69, and a compression spring is between said head and the wall of easing 5i holds the plunger and the piston in normal retracted position with the piston in engagement with a stop H, punched up from tubular member 59 to leave an air vent 12, Fig. 5. The piston 68 will have a normally sealing fit with the inside of passageway 60. The piston will however cooperate with a channel 13 extending from chamber 56 to passageway 58 and cooperating with some form of cavity in piston 68 when it is in its normal retracted position. As shown in Fig. 5, this cavity may be an annular or semiannular groove 14 which has a portion underlying channel 13 in the retracted position of the plunger and a portion overlying opening'BG in the projected position of piston 68. As shown in Fig. 7, the cavity of piston 68 may be a transverse bore or hole I5 which will directly underlie passageway 13 in the retracted position of piston 68 and will overlie the opening 66 to tube 63 in the projected position of piston 68.

Or, as shown in Fig. 8, a cup-like cavity 98 may be provided in a rotatable piston 9| on stem 61 opening from 13 in alinement with opening 66 and the member 9| being adapted to rotate a half turn to drop the liquid held in cavity into opening 66.

Whatever form of cavity is employed it will be understood that it will cooperate in one position with passageway 13 to receive a requisite charge of incense liquid when the piston is in retracted position, and will cooperate with opening 66 when the piston is in projected position to discharge the predetermined quantity of liquid to passageway 63 down which it will gravitate into pan 62 to form a film over the surface of said pan. Since all parts of piston 68 except the cavity-channel part make a sealing fit, no incense liquid can pass through excepting when the piston is operated and then only the amount which is predetermined by the size of whatever form of cavity is employed.

The pan 62 will have associated with it in any desired known manner, electrical heating means whereby the pan, and particularly its bottom portion, may be suitably and speedily heated. The pan is shown supported by means of brackets 15 and Ti secured to casing 5| as shown in Fig. 6 and these brackets support not only the pan but the heating elements contained in a block 18. A circuit is adapted to be closed by self-retracting plunger switch 19 causing current to pass through wires 88, BI and 82 from feed cable 83.

The advantages of our invention will be apparent. Whichever form is employed a limited amount of incense liquid will be caused to be delivered upon the surface which is to be heated. The heating of this surface electrically effects quick and voluminous discharge of the fumes of the incense liquid which pass out through the holes ail of the casing section. There will thus be vaporized almost immediately exactly the right amount of liquid to furnish the requisite amount of incense vapor for the desired effect.

We claim:

1. An electric incense vaporizer comprising a casing formed with two chambers, a receptacle for incense liquid toward the top of one of said chambers, an electric heater including a pan toward the bottom of the other of said chambers, means forming a passageway from said receptacle to overlie the pan, an interceptor comprising a piston formed with a cavity extending from one side to the other of said piston, means holding said piston normally so the cavity is presented to the passageway coming from the receptacle, and means to project the piston to bring the cavity into alinement with the passageway leading to the pan.

2. An electric incense vaporizer comprising a casing formed with a receptacle for incense liquid toward the top of the casing, a pan toward the bottom of the casing and an electric heater for heating the same, means forming a passageway from said receptacle having a discharge orifice directly overlying the pan, an interceptor in said passageway having a cavity normally presented to the part of the passageway leading to the receptacle, and manual means to move the interceptor to a position where the cavity will be opened to the discharge orifice so that the predetermined amount of liquid in the cavity will be discharged from said orifice to fall by gravity upon the pan.
